Good start
The app is a good start and is reminiscent of something that I might have made for a computer science project. To make this better, I would recommend speeding up control feedback, or how long it takes for a control to go from touch to movement. Also, holding altitude while moving in any direction seems impossible. I would add point to go to, like rings you have to fly through. I would also add obstacle courses and other maps.good start, and could be useful to get people interested in quadcopter flying.
